GAGE FOR PAPER-FOLDING MACHINES.

Specification of Letters Patent.

Application filed June 22, 1912.

Patented Mar. 1'71, 1914. Serial No. 705,323.

To all 'ltZLOI/L it may concern Be it known that l, CLARK A. SIGAl-UUS, a citizen of the United States, and a resident of Omaha, in the county 01'? Douglas and State of Nebraska, have invented certain new and useful improvements in (lages for l a erl olding Machines. of which the following is a specification.

My invention relates to paper folding machines and more particularly to the gaging and guiding devices for such machines.

It is the object of my invention to proride in a paper :t'ohling machine a paper gaging device oi simple and inexpensive cmistruction, which may be quickly and easily adjusted to dijtl'erent positions relative to the carrier-belts, and guiding devices for the paper arranged so as to be supported by the gage at any of its adjusted positions.

In the accompanying drawings Figure 1 is a side view of a mechanism embodying my invention, Fig. 2 is a plan view thereof, Fig. 3 is an end View of the same, and Fig. %l is a detail sectional view thereof on the plane of the line of Fig. 1.

In the drawings there is shown a portion 1 of the main frame of a paper folding ma chine, and also portions of bars 2 and 3 which are fixedly connected with the main frame and extend transversely to the particular set of carrier-belts for which the gaging device shown is used. It will be understood that any number of the gaging devices may be used on one folding machine, all being arranged in substantially the same manner, relatively to the respective sets of carrier-belts, as that shown. Portions only of a set of carrier-belts 4i are shown in the drawing, the said belt-portions passing around a main driving roller 23 and small pulleys 5, said pulleys 5 being journaled in the forked ends of bars 6 which extend through brackets 7 secured on the bar 2, and the bal's 6 having tensioning springs 8 disposed upon the outer end portions thereof and engaging the brackets so as to maintain a constant tension upon the belts 4t. On the frame portion 1 is secured a standard 9 and in the upper end of the standard is secured a rod 10 which extends above and parallel to the belts l. In the lower part of the standard just above the frame 1 is formed a long bearing for a rod 11 which passes revolubly through the bearing and extends below the plane oi. the carrier-belts and parallel to the rod 10. The inner portion of gaging the inner end ol' the bearing.

the rod is threaded and a nut 19 is screwed thereon so as to form an abutment for en- ()n the outer part of the rod a pin 13 is passed through it and :ul ioining the pin is placed a washer it between which and the outer :lace oil, the standard is placed a coil spring 15. The spring presses against the washer and thus pushes the rod outwardly so that the nut 19 is held yieldingly against the inner end of the hearing. A. pin 16 is passed through the rod near the outer end thereof, said pin being adapted for engagement with the notched end ot a removable crank 17 which is employed for turning the rod. A head 18 its slidably upon the rod 10 and in the lower part of the head is a threaded opening through which the rod Ill is screwed. On the upper part of the head 18 and extending transversely just above the upper sides of the carrier-belts is the gage-plate 19. At positions between the carrier-belts the ends of the deflecting lingers 20 are secured in the gage-plat and the said fingers extend inwardly therefrom, being at first parallel to and slightl above the belts, and near their ends being inclined downwardly so that said ends terminate below the upper sides of the belts. On the bar 3 are secured heads 91 with which are connected the ends of the guide-rods 22. the said rods curving downwardly from the heads to aid the roller and then extending back parallel with and slightly above the carrier-belts. The rear ends of the guide-rods pass slidably through openings made therefor in the gage-plate 19 and are supported and held in position by the plate.

The operation of the mechanisn'i will be apparent. The carrier-belts move in the direction indicated in Fig. l and on their upper surfaces the sheets of paper delivered to them are conveyed toward the gage device. The paper passing under the rods 22 is thereby prevented from curling or being blown upwardly by air currents so as to get out of its proper relation to the belts. As the forward edge of the paper passes the ends of the fingers 20 the inclined portions of the fingers deflect it slightly upward so that it is raised slightly above the belts and prevented from passing under the gage-plate. The edge of the paper thus meets the gage-plate squarely and is positively stopped thereby. To change the position of the gageplate it is merely necessary to place the crank 17 upon lit) the end of the rod 11 and turn the same until the head 18 and gage-plate are moved to the desired position, the guide-rods 22 and deflecting fingers 2O meanwhile retaining their same relative positions so that the operation of the device is unaltered by the adjustment. The abutment-nut 12 being held against the end of the rod-bearing by the spring 15, makes a frictional retaining device which serves to retain the screw-rod 11 in its adjusted positions, while the yieldable connection of the rod with the standard 9, afforded by the spring 15, allows the screwrod to accommodate itself more or less to any accidental variation or deflection of the support-rod and thus prevent the head 18 from binding or sticking upon the support-rod so as not to slide easily thereon.

Now, having described my invention, what I. claim and desire to secure by Letters Patent is:

1. In a paper folding machine, carrierbelts, a gage-plate extending transversely to the belts, means extending parallel to the belts. for supporting the gage-plate, a screw connected with the gage-plate for moving the same longitudinally of the supporting means, and fingers secured to the gage-plate above the carrier-belts and having end-portions extending below said belts to deflect papertherefrom against the gage, the said fingers being in a constant fixed relation to the gage at all positions thereof.

2. In apaper folding machine, the combi nation with continuously moving carrying devices, of a gage extending transversely to the direction of movement of the carrying devices, means. for supporting the gage,

means for varying the position of the gage longitudinally of the carrying devices, and fingers secured to the gage and adapted to deflect paper from the carrying devices against the gage, the fingers being in a fixed constant relation to the gage at all positions thereof.

3. In a paper folding machine, the combination with carrier-belts, of a gage disposed above the belts and extending transversely thereto, a head supporting the gage and extending vertically between the belts, rods extending parallel to the carrier-belts and supporting the head, one of said rods being screwed through the head, guide-rods extending above the carrier-belts, one end of each of the guide-rods being slidably connected with the gage, and means for deflecting paper from the carrier-belts against the gage.

4. In a device of the class described, the combination with carrier-belts, of a gage positioned adjacent to the belts, a frame, parallel rods supporting the gage, one of the rods being revolubly mounted and the other fixedly mounted on the frame, the revoluble rod having a threaded connection with the gage, means for turning said rod to vary the position of the gage longitudinally thereof, and yieldable means for holding said rod in frictional engagement with the frame.

In testimony whereof I have hereunto subscribed my name in the presence of two witnesses.
